You can try something like below (change with conditional statements to fit=
 your requirements of upto 2 numbers):

class Time
  def duration
    Time.now - self
  end
  def duration_string
    difference =3D duration
    days =3D (difference/(3600*24)).to_i
    hours =3D ((difference%(3600*24))/3600).to_i

    mins =3D ((difference%(3600))/60).to_i

    secs =3D (difference%60).to_i
    "#{days} days=2C #{hours} hours=2C #{mins} minutes and #{secs} seconds"
  end
end

start =3D Time.new
sleep(5)
puts start.duration_string
